Rice University Claims It Can Double Wireless Capacity

[Guest]

Researchers at Rice University have developed a new technology that enables cell phone devices to both "talk" and "listen" to wireless cell towers on the same frequency.

Must resist asian joke...

Rice University...............
That would be nice if they had a lttle background to this university so we wouldn't have to google around for it.
From the names of the people here, it definitely sounds like an asian bunch, but what else has this university come up with would be nice to know.
Theories......??? I guess, 99% of us here at Toms, have Theories about everything starting from kids nappies to the space station MIR, I don't think it'd be very advisable to be writing articles on everyone's theories.....

Thanks Eggheads.

I have a friend who goes to rice university. She's Asian. Along with most of her friends there.

Rice University is in Houston, Texas, named after William Marsh Rice; its origins are whiter than rice. It's a strong university with an emphasis on engineering; there's a very active nanotechnology group that does a lot of work with the nearby medical research facilities in Houston.

Some people here must be really bad at using google...

Anyway, full-duplex has been around for a while, hasnt it? Just not for cell phones? Also, are they already planning to upgrade to 4.5g/5g when so much of the country still doesnt have 4g? And beyond that when people that do have 4g cant use it for long because of data caps?

Can't stop thinking of DIDO wireless

For those not familiar...Rice university is an extremely well regarded engineering university in Texas. They are pretty Ivy league quality just do not meet the criteria. If you graduate from Rice with an engineering degree you will not have trouble finding a job unless you are a complete idiot

Actually, Rice University also has a fantastic MBA program!

@ scook9

- Why do you insist that having a college degree, let alone one from Rice University, creates a sense of job entitlement? Yes, I get it, Rice is prestigious, well-respected and all-around awesome. But it's the college grad's responsibility to actually lift a finger and convince employers he/she is the best candidate based on academic credentials & work experience. Having (any) college degree doesn't mean the success will be spoon fed to you.

Wow for those who dont understand wireless, know this: Full duplex on the same frequency is in fact, undone at this point in the market. Currently, there is ONE way to achieve a full duplex radio transmission: Use 2 frequencies.
That said, are there some things that seem full duplex? Certainly. WiFi for one. However, the AP and the clients are never talking at the exact same time. Time in this case being very small, so the transition goes unnoticed. Real example a 802.11n AP at HT40 is a max 300Mbit link. With really great equipment, you can get very close to 300mbit in one direction. Do a full duplex transmission, and it will get around 150 up, and 150 down.. close to the actual 300.. This is because now the AP is trying to send, and so is the client, so they have to take turns. Thus, a 50% reduction in non-aggregated throughput, but still an aggregate equalling the maximum of the technology.
With the technology outlined above, said WiFi could theoretically send 300mbit, and receive 300mbit at the same time. Raising the aggregated bandwidth to 600 (albeit that you wont get 600 in ONE direction). Effectively doubling it.
MIMO antenna arrays currently make a difference by changing the polarity and using a different modulation point for transmission, but are still not full duplex. In the case of cellular companies, if they used this, they could handle double the traffic in a given area, with the same spectrum allocation they currently have, which in this case would help AT&T more than acquiring T-Mobile as far as spectrum is concerned.

Hmmmmm :\ From article it seems like they have invented full-duplex communication mode, which has been around almost as long as telephones are.

Bet you all the money in the world ... China implements the technology first!
